THREE SMALL STEPS
How to validate a phone number
-
01
Choose the country
Pick the country, or start the number with + and its country code to detect it automatically.
-
02

Enter the number with or without spaces, brackets and dashes. The result updates as you type.
-
03
Use the right format
Copy the E.164 format for databases and messaging tools, or the international format for display.
Good to know
Valid is not active
A valid number follows its country’s rules. The tool does not call it, so it cannot tell whether the line is in service.
Private check
The number is checked in your browser and is not sent to any server or lookup service.
QUESTIONS
Frequently asked questions
Does a valid phone number mean it is active?
No. Validation checks the numbering rules for the selected country. It does not call the number, send an SMS or confirm who owns it. Use the E.164 result when you need a standardized international representation.
What is the E.164 format?
E.164 is the international standard format: a plus sign, the country code and the number, without spaces, such as +33612345678.
Why is my number marked as not valid?
Check the country, the number of digits and the prefix. A number written with a national 0 needs the right country selected, or + and the country code instead of the 0.
Can it tell mobile numbers from landlines?
Yes, when the country’s numbering plan separates them. In some countries, such as the United States, the same prefixes serve both, so the type shows as landline or mobile.
